NEW BOX CULVERT
LORIMER ROAD
Purpose of Project
3 | Lorimer Road Petition Project Public Meeting
To address:
• Roadway Deficiencies
• Pedestrian Safety & Connectivity
• Aging Infrastructure
• Stormwater Runoff Issues
• Local Interest To Add Sidewalks
Roadway Deficiencies
4 | Lorimer Road Petition Project Public Meeting
• Constructed in 1950’s without design standards• Narrow street in rolling terrain with steep slopes• Old pavement is nearing the end of service life
Roadway Deficiencies
5 | Lorimer Road Petition Project Public Meeting
• Visual obstructions - trees limit sight distance• Fixed-object tree hazards along the roadway• No sidewalks or usable shoulders for pedestrians
Pedestrian Safety
6 | Lorimer Road Petition Project Public Meeting
• Incomplete sidewalks & pedestrian connectivity • Pedestrians forced to walk in travelway • No pedestrian connection to schools & churches
Aging Infrastructure
7 | Lorimer Road Petition Project Public Meeting
Typical box culvertservice life is 50 years
Existing culvert is over 55 years old
Aging Infrastructure
8 | Lorimer Road Petition Project Public Meeting
• Concrete spalling - exposing steel reinforcement
• Encased gas & water utility lines attached under deck surface - not permitted by today’s standards
Stormwater Deficiencies
9 | Lorimer Road Petition Project Public Meeting
• High water velocities and flooding • Existing roadway ditches show isolated erosion• Ditch erosion carries sediment to Bushy Creek
Original Roadway Section
10 | Lorimer Road Petition Project Public Meeting
• Remove and replace the existing pavement
• Construct a curb & gutter section with 11’ lanes
• 5-foot sidewalk, 6-foot green space on the west side
• 3.5-foot berm on the east side
Original Project Approach
11 | Lorimer Road Petition Project Public Meeting
• Roadway side slopes designed to minimize the construction footprint
• Add new driveway aprons and matching driveway surface material
• Remove & Replace the Bushy Creek Box Culvert
• Add a new storm drain system to minimize the use of roadside ditches
• New storm drain system will be designed to separate roadway surface runoff from offsite stormwater
Sample Level Spreader
Public Meeting #1
12 | Lorimer Road Petition Project Public Meeting
Summary of Comments & Concerns:• Reduce sidewalk setback & construction footprint
• Tree Loss & Property Value Loss from construction
• Hire an Arborist to assess impact to trees
• Eliminate existing roadside ditches
• No level spreaders, save trees
• Special Considerations (driveways & walls)
Response To Comments
13 | Lorimer Road Petition Project Public Meeting
Design Revisions:• More Parcels w/ Reduced Sidewalk Setback
• Reduced Construction Footprint
• Eliminated Level Spreaders
• Eliminated Existing Ditches Along Lorimer Road
• Upgrade Street to Current Fire Protection Standards
• Added a Project Arborist w/ City Urban Forestry Division
Reduced Setback Width
14 | Lorimer Road Petition Project Public Meeting
• Reduced the Setback to 3.5’ on Nine (9) Parcels
• Increased the Setback to 11’ for One (1) Parcel to avoid a Power Pole
• Added a Retaining Wall to Parcels 1400 & 1402
• West Side Impacts Reduced by: 0.3 Ac.Original Design - 0.9 Ac.Revised Design - 0.6 Ac.
Eliminated Ditches
15 | Lorimer Road Petition Project Public Meeting
• Extended 3.5’ Berm To Fill Existing Ditches
• Eliminated Rock Lined Ditches
• Use Erosion Control Matting for Toe Protection
• Eliminated level spreaders
• Direct discharge to Bushy Creek from new storm system (same as existing) Erosion Control Matting
Toe Protection
Fire Protection
• Reduced Fire Risk
• Increase property value
16 | Lorimer Road Petition Project Public Meeting
• Lorimer Rd has Five (5) fire hydrants from Kaplan to Garland
• One fire hydrant every 500’ to 1000’
• Upgrade to current fire protection standards
• One fire hydrant / 400’
• Add Three (3) new fire hydrants on Lorimer Rd
New Fire Hydrants
• Urban Forestry Division w/ ISA Certified Arborist
• Field survey of Location, Size, & Species
• Assess Tree Health (good, diseased, dead)
• Assess Hazards (utility conflicts, safety)
• Provide guidance for tree protection and removal
Arborist Involvement
